VARIABLE BANDWIDTH STRIATED CHARGE FOR USE IN A ROTARY VANE PUMPING MACHINE

摘要

This rotary vane combustion engine (400) includes a rotor having a plurality of vanes (120); a stator enclosing the rotor (100) to form a plurality of vane cells (140) between the plurality of vanes (120); one or more intake ports (540) for providing intake charge to the vane cells; one or more exhaust ports (543) for removing exhaust gas from one of the vane cells; and a variable bandwidth fuel-air source (W) connected to at least one of the intake ports (540) for providing a discrete band of mixed fuel and air having a desired axial width to each of the plurality of vane cells (140). The rotary vane combustion engine (400) will allow the machine or engine to run at lower power without requiring it to runa vacuum to lower the density of mixed fuel and air. Therefore, vacuum-pumping losses are eliminated and the machine/engine operates more efficiently.
